Intelligent wireless dissolved oxygen measuring instrument

The intelligent wireless dissolved oxygen measuring instrument uses a galvanic oxygen sensor to monitor the dissolved oxygen concentration in water, and is mainly used for real-time online measurement in places such as breeding and water quality monitoring. The system takes micro-processing as the core and has self-calibration and compensation functions of temperature, atmospheric pressure and salinity. It has accurate measurement, fast response speed, good stability and can work reliably for a long time. The system uses NB-IoT wireless wide area network communication technology, and the data is sent to the cloud platform through the Internet of Things. It also displays information such as dissolved oxygen, water temperature, and local atmospheric pressure, making the system convenient and fast to use.
